Description

Technical Field

[0001] This utility model relates to the field of chemical experimental reaction tube technology, specifically to a multifunctional experimental tube that facilitates gas replacement. Background Technology

[0002] Existing Srank tubes used in laboratories have significant structural defects in gas replacement operations. The glass stoppers in commonly used reaction tubes require the use of silicone grease as a lubricant, which leaves residue in the separated products and is difficult to remove. Furthermore, the main body of existing Srank tubes requires a complex three-way assembly system: one end has a movable plunger for adjusting the gas output, and the other end is connected to a vacuum pump via a rubber hose for evacuation. This multi-component parallel structure is complex to assemble and inconvenient to use.

[0003] Therefore, it is necessary to provide a multifunctional experimental tube that facilitates gas replacement by allowing gas output control through a single side tube. Utility Model Content

[0004] The main purpose of this invention is to provide a multifunctional experimental tube that facilitates gas replacement, in order to solve the problems existing in the prior art.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A multifunctional experimental tube for easy gas replacement includes a main body with an inner wall frosted structure at the upper end for connecting other devices. A branch pipe is provided on the side wall of the main body, and a flared portion is provided on the branch pipe. A gas flow regulator is also connected to the branch pipe, and one end of the gas flow regulator extends to the flared portion.

[0007] Furthermore, the branch pipe is provided with a threaded structure, and the gas flow regulating component is connected to the threaded structure.

[0008] Furthermore, the gas flow regulating component includes a rotating drum, a plunger, and an outlet pipe. The rotating drum is provided with a threaded line adapted to the threaded structure. The rotating drum is threadedly connected to the branch pipe. The plunger is connected to one end of the rotating drum and inserted into the branch pipe. The outlet pipe is connected to the end of the rotating drum away from the plunger. The plunger is provided with a vent hole and communicates with the outlet pipe.

[0009] Furthermore, the air outlet pipe is provided with a barbed structure.

[0010] Furthermore, the branch pipe is a straight pipe.

[0011] Furthermore, the top end of the main body is provided with a threaded opening, and a cap is threadedly connected to the threaded opening.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The main body can be directly connected to the gas flow regulator through the branch pipe to achieve stable adjustment of the gas output, making the overall structure simpler and easier to operate; the upper port of the main body is equipped with an inner wall frosted structure, which facilitates the connection of other experimental devices to meet the needs of various experimental purposes.

[0014] When in use, simply turn the drum. As the drum moves, it moves the plunger. The depth to which the plunger is inserted into the branch pipe can change the size of the air outlet space, thereby controlling and adjusting the air output. It is practical and convenient.

[0015] By rotating the gas flow regulator onto the branch pipe with the rotation center being the axis of the branch pipe, it can be ensured that the force on each part is uniform during rotation.

[0016] The structure of the branch pipe with flared end and gas flow regulating component can prevent solid powder from being drawn into the rubber tube or vacuum pumping structure. Attached Figure Description

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0020] Example 1

[0021] Combination Figure 1 This invention provides a multifunctional experimental tube for easy gas replacement, comprising a main body 1. The upper end of the main body 1 has an inner wall frosted structure, which is used to connect other experimental devices to achieve multifunctional experimental purposes. A branch pipe 2 is provided on the side wall of the main body 1, and the branch pipe 2 has a flared portion 3. A gas flow regulator 4 is also connected to the branch pipe 2, and one end of the gas flow regulator 4 extends to the flared portion 3. The flared portion 3 facilitates the entry of gas from inside the main body 1 into the gas flow regulator 4.

[0022] In this embodiment, branch pipe 2 can be a Young's tube with a flared structure. Young's tube is an existing design and will not be described in detail in this embodiment.

[0023] The branch pipe 2 is provided with a threaded structure, and the gas flow regulating component 4 is connected to the threaded structure. The gas flow regulating component 4 is provided with a thread that is adapted to the threaded structure. By turning the gas flow regulating component 4, its relative position with the branch pipe 2 can be adjusted, thereby adjusting the depth of the gas flow regulating component 4 inserted into the flared part 3, adjusting the size of the gas outlet space, and thus controlling the gas volume.

[0024] The gas flow regulating component 4 includes a rotating cylinder 41, a plunger 42, and an outlet pipe 43. The rotating cylinder 41 is provided with a threaded line adapted to the threaded structure. The rotating cylinder 41 is threadedly connected to the branch pipe 2. The position of the rotating cylinder 41 relative to the branch pipe 2 can be adjusted by turning the rotating cylinder 41. The plunger 42 is connected to one end of the rotating cylinder 41 and is inserted into the branch pipe 2. The outlet pipe 43 is connected to the end of the rotating cylinder 41 away from the plunger 42. The plunger 42 is provided with a vent hole 5. The plunger 42 is connected to the outlet pipe 43. The gas in the branch pipe 2 enters the plunger 42 and the outlet pipe 43 in sequence through the vent hole 5.

[0025] The air outlet pipe 43 is provided with a barbed structure, which facilitates the connection of an external rubber tube and increases the resistance to pulling the rubber tube outward, making the rubber tube connection more stable and improving the connection sealing performance.

[0026] The branch pipe 2 is a straight pipe, which is directly connected to the main pipe 1, effectively increasing structural strength. In some other embodiments, the straight pipe and the main pipe are integrally formed. By rotating the gas flow regulating component 4 onto the branch pipe 2, with the rotation center being the axis of the branch pipe 2, it can be ensured that the force on each part is uniform during rotation, reducing the occurrence of damage caused by uneven force on components.

[0027] The top end of the main body 1 is provided with a threaded opening, and a cap 6 is threadedly connected to the threaded opening.

[0028] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
